Heppner (2001) Lecithoceridae (Lepidoptera) of Taiwan (IV): Subfamily Torodorinae: Genus Deltoplastis Meyrick. Zoological Studies 40(1): 44-48. Three species belonging to the genus Deltoplastis of the subfamily Torodorinae are recognized from Taiwan, including a new species: Deltoplastis ovatella sp. nov.. D. lobigera Gozmány is reported for the first time from Taiwan. A key to the species is provided. Key words: Systematics, Description, New species, Deltoplastis, Taiwan.
